4 Claims.

v This invention relates to a locking means for a totalizer. It has frequently been found that unauthorizedpersons will maliciously attempt to change the amount setup on a totalizer by in- 'serting a screw driver or other means to rotate thetotalizer pinion. This might be done by a dishonest clerk. If he could set back the ten dollar totalizer wheel one point he would be en- 'abled to knock-down $10.00 and pocket the same A and thereby perpetrate a fraud on the proprietor. 'The object of this invention is to provide a positive locking means to prevent such unwarranted f manipulation.

r For purpose of illustration I have shown the same in connection with that type of totalizer shown in the patent of Albert S. Wheelbarger and Grover C. Coil, No. 1,876,118, patented September 6, 1932.

"In the drawings:

'20 1 Figure 1 is a side elevational view of a machine such as shown in the said patent.

T Figure 2 is a plan view of the totalizer. Figure 3 is a side elevational view, partly in 'orosssection, on the line 3-3 of Figure 2.

'25 Figure 4 is a perspective view of the control member, and

Figure 5 is a perspective view of certain of the z parts shown in Figure 3.

' In the said patent the differential gears I are 5 i'otatably mounted on a shaft 2 and the totalizer -'pinions 3 are moved into engagement with the difierential'gears 'on the adding operation and are disengaged therefrom on the return movement'of the differential gears. This is accomplis'hed by the rotation of a shaft 4, which is the main driving shaft, of the machine on which are mountedtwo cams 42 and 43 which are rotated 'inthe direction of the arrow (Figure 1). The ""lever'44 is pivoted on a pin 45 and is urged to .40 theleft as viewed in Figure 1 by means of a spring 14 having its other end secured to the frame of the machine, which lever is provided with a roller 46. The upper end of the lever 44 "is bifurcated and receives a pin 48 carried by a. 45 crank arm 49 securely mounted on a shaft 59, which' shaft carries a crank arm 5i which carries a pin 52received in a bifurcation in the end of the bell crank lever 53 pivoted on a shaft 54. The lever'53 carries awn-55 which is received 1 50 arm 56 rotatably mounted on the shaft 54.

'="" nsng 1ever 4l which' isvprovided with a carrying nose 59. There are, of course, as many carrying levers as there are totalizer pinions 3 except that there is no carrying lever operated by .the totalizer pinion of highest denomination. When one of the carrying levers 41 is in the po- 68 which will receive a laterally extending lug 63 on the carrying lever 41 when the said carrying lever is fully elevated. Each of the tripping pawls 61 is normally urged into the position shown in Figure 5 by means of a spring 69 connected to a crossbar Each of the tripping levers 51 is provided with a forwardly extending 'arm 10. terminating in a downwardly extending nose 'II.

As soon as the shaft 4 commences its rotation the cam43 engages the roller 46 on the lever 44 moving the upper end thereof to the right as viewed in Figure I. The cam 43 is provided with a lobe 5 which extends a short distance beyond the outer periphery of the cam 43. This lobe moves the lever 44 the maximum distance in a clockwise direction as viewed in Figure. I, thereby moving the arm 49 and shaft 50 rotating the arm 5I in an anti-clockwise direction as viewed in the said Figure I, which elevates the arm 56 raising the holding member 51. The holding member 51 underlies and engages all of the carrying levers 41, raising them until the laterally extending lugs 63 are elevated beyond the shoulders 68 and the springs 69 move the said shoulders beneath the said lugs. Immediately thereafter the lobe 5 passes beyond the roller 46 and the carrying levers 41 are thereby permitted to descend a short distance, being pulled downwardly by means of the springs 6| which connect the carryingv arms 58 and cross bar 60. The laterally extending lugs 63 now engage the shoulders 68. The lower ends of the tripping levers 61 are in the path of rotation of the carrying teeth 96. The carrying teeth are so positioned on the sides of the totalizer pinions 3 that they will engage the tripping levers 61 as soon as the totalizer pinions 3 pass beyond the position in which they would be wheen set to represent the numera1 9. It will, of course, be understood that there ing member 5?.

is one such carrying tooth on each totalizer pinion. When the lobe E has passed beyond the roller 46 the said roller rides on the periphery of the cam 53 and the spring 74 holds the said roller in engagement with the periphery This slight downward movement of the holding member 5? does not only allow the laterally extending lug 63 to engage the shoulder 68, as above mentioned,

roll off the cam 43 and the spring M will move the lever 44 to the left as viewed in Figure '7 and lower the holding member 51 so that the spring 6| can move the carrying nose 59 of the lever 41 into engagement with the totalizer pinion of next higher order and rotate it one notch provided,

7 of course, that the carrying tooth 96 of the totalizer wheel of the lower denomination has engaged the tripping lever 61 and released its shoulder from beneath the laterally extending lug 63.

The cam 42 engages a roller 13 rotatably 'mounted on a pin 12 carried by a lever 6 which is pivoted on the shaft 45. The lever 6 is urged to the left as viewed in Figure l by means of a spring 15. This lever carries a pin 16 at its outermost upper end, which pin is connected to a pin 11 on a crank lever 18 by means of a spring '19.

The crank lever 18 is secured to a shaft 80, which shaft carries a plurality of crank arms 8| which are bifurcated at their upper ends and receive the shaft 27 carried by the frame members 25. It will be noted that the roller 13 does not engage the cam 42 until some little time after the cam Q3 has engaged the roller 46. The object of this construction is to give the cam 43 sufficient time to elevate the carrying levers 41 and for the holding member 51 to drop slightly below its highest position'pafter' the roller 46 has passed the lobe 5; The eam 42 then engages the roller "1 3 and rocks the crank arms 8| inwardly or counter-clockwise as viewed in Figure 1 so as to move the totalizer frame to the leftas viewed in the said figure so as to engage the totalizer pinions 3 with the difierential gears I; this movement being permitted by the slots 33 in the fixed 3 frame 28, which slots engage the guide shaft 3!.

At approximately degrees thereafter the cam 42 passes beyond the roller i3 and the spring 15 moves the totalizer frame and totalizer pinions to :the right as viewed in Figure 1 so that the subtracting movement of the differential gears i will not be imparted to the totalizer pinions 3.

A control member i is rotatably mounted on a shaft 8, which control member is provided with two V-shaped slots 6 and i6 and a rectangular shaped slot 1 i, all of which slots run substantially lengthwise of the control member I; that is, the boundary line of the slot 9 nearest to: the slot H is parallel with the long sides of the slot ll and the boundary "line ofthe slot l0 furthest removed from the slot H is parallel to the'long sides of the slot i i while the other long bounding side of the slots 9 and i6 extend at an angle to the sides of the slot II. This relation between the slots 9 and H is very clearly shown in Fig ure 4;

A lever i2 is pivoted on the shaft 2 and is provided witha nose t3, the forward end of which is blunt and the rear end of which is sloping, This 1 nose extends within the slot l i and is held therein by means of a spring i4 having its other end secured to a fixed pin 15 secured to the framework of the machine. A pin #5 is carried by a lever l'i pivoted on the shaft 5 3 which lever is provided with a nose [8 which engages a. cam 89 on the shaft 26 on which the totalizer pinions; are rotatably mounted. When. the shaft 26 is reset counter-clockwise as viewed in Figure l the cam is elevates the lever if and pin it, which pin, as shown in Figure 3, engages beneath a tail 2! of a yoke 2 2,'which yoke overlies all of the arms i0, as well as levers 23 provided with tails 24 to which are securedsprings 26, the spring 2Q tending to keep the yoke 22 elevated above the arms i0 and levers 23 but when the machine is being reset the pin [5 would depress the yoke 22 and lower the arms 78 and levers 23.

Holding dogs 36 are pivoted on a shaft 32 and are provided with noses 35 which engage between the teeth of the totalizer pinions. The dog 36 is provided just above the nose 3d witha lug 35 on"- which is mounted a spring 36 which has its upper end anchored in a pin 37 on abar 35 mounted on: the shaft 29 and above a cross bar 39. The only function of this bar 39 is to provide a rigid support for the pin 3'1. The right hand end of the lever 23 is provided with a nose 4!! which projects within a slot ii of the control member I.

There is only one lever 23 but there are as many-- tripp-ing levers 6?, arms l6,bars38, carrying levers ti, and dogs 36 as there are differential gears i.

In operation the parts are normally as shown in Figure 3. The noses E2 of the holding dogs'30" are closely adjacent to the outer periphery of the control member '5 and the nose 34 of each of the holding dogs positively locks each of the totalizer pinions against rotation in any direction. The operator may-insert a screw driver and attempt.

to rotate these totalizer pinions or any one of them but he simply forces the nose 62 against the periphery of the holding member i but he has not succeeded in removing the nose 34 of each of'the dogs from'engagement betweentheteeth of the;

pinions and they, therefore, cannot-be rotated.

He can, however, reset the totaliaer pinions by rotating the shaft 26 by any suitable means which form no partof this invention and is, therefore, not shown, which will rotate the earn [9 and-elevate the lever H and pins iii which extend beneath the tail 2! of the yoke 22 which extends over the'lever 23 and over all of the arms in, thereby depressing the said lever 23 and arms 76.

As the lever 23 is depressed, since its nose 46cm gages in the slot 4|, it will rotate the control member I anti-clockwise as viewed in Figure 3 so that the slot It! will be beneath the noses H of the arms iii and the slot 9 will be adjacent the noses 62 of the dogs 36. Since the dog '35 is. now only yieldinglyr held against the totalizer pinions and does not lock them, the totalizer pinionsfcan be rotated. As this rotation occurs the totalizer wheels may, therefore, be reset in the conventional manner. 7 1

In the normal adding operation of the machine it will be remembered that the totalizer pinions are moved into mesh with the differential gears I at the commencement of the operation of the machine. The left hand end of'the lever l2 (Fig-' ure 3) engaging in the slot I! will rotate the control member '5 so as to bring the slot l0 beneath the noses H of the arms 16 and to bring the slot 9 adjacent the noses'62 of the dogs 30. a It will also be remembered that thelobe 5' of-the cani 43 has elevated the lugs 63 of the carrying levers 41 so that they are engaged above the shoulders 68 of the tripping levers 61 and that as soon as the lobe 5 passes the roller 46 the holding member 51 is slightly lowered. If the differential gears are now operated, being in mesh with the pinions 3, the pinions 3 will be thereby actuated and it may be that a carrying operation will be necessary. If there is any carrying, the pinion of lower denomination, having a carrying tooth 96, will engage the tripping lever 61 and move it to the left as viewed in Figure 3 so as to release the shoulder 58 from beneath the lug 63 and the carrying lever 41 will then drop a short distance until it is stopped by the holding member 51, which distance is not sufficient to carry to the totalizer pinion of next higher order. If the carrying tooth 96 moves the tripping lever 61 as just described, the nose H of the arm 10, which is integral with the tripping lever 61 will be forced into the slot I 0 by the carrying tooth 96. At the end of the adding operation, but before the carrying has taken place, there may be none or any number of the noses H extending within the slot III, depending upon how many totalizer pinions have passed the carrying point. Towards the end of the operation of the machine the totalizer pinion is Withdrawn from the differential gears as heretofore described and shortly thereafter the cam 43 passes beyond the roller 46 and the holding member 5! is permitted to fall to its lowermost position so that the carrying noses 59 of any of the carrying levers 47 which have been released by the carrying tooth 96, releasing the tripping lever 61, will engage the pinion of next higher or der and rotate it one point, thereby carrying. It may sometimes be, however, that this carrying of I will have to be carried through a number of the totalizer pinions. For instance, if I is added to 999, not only do we have to carry from units to tens, but from tens to hundreds and from hundreds to thousands. In the above example, only the units carrying tooth 96 would have released 41 which would actuate the,

the carrying lever tens counter on the carrying operation and all of the other carrying levers 4'! would be retained in their elevated position; that is, with the nose 63 engaging the shoulder 68. When, however, the tens wheel is rotated, as just mentioned, its carrying tooth 96 would engage a tripping lever 67 and would release its carrying lever 41 which would carry to the hundreds. This requires, however, that the arms 10 should be permitted to enter the slot l0 and it will be remembered that the lever I2 will no longer be holding the control member 1. However, in the above example, the tens nose II would be engaged in the slot l0 and when it is released by the carrying tooth 96 passing beyond the lever 61 and the hundreds wheel is now moving, the nose 62 of the dog 30 would be in the slot 9, which thereby holds the control member 1 against moving back to its initial position. It is this alternate movement of the noses II and 62 into and out of the slots I0 and 9 that keeps the control member from being rotated back to its normal position. The slots are made V- shaped so as to assure that the noses would readily enter the slots and not strike against the side thereof so that the control member 1 during the various carrying operations would act somewhat as an escapement member moving progressively towards its normal position as succeeding transfers occur. When all of the noses H are released from the slot 10, the spring 26 pulls the lever 23 upwardly and thereby rotates the control member back to the position shown in Figure 3.

It is obvious that many changes may be made in the specific form of the invention shown in this application and I, therefore, desire to claim the same broadly except as I may limit myself in the appended claims.

Having now described my invention, I claim:

In a machine, a plurality of totalizer wheels, actuating means therefor, means to move said totalizer wheels into engagement with said actuating means, a rotatable control member having a groove therein, a plurality of locking means normally engaging the periphery of said control member and engaging each of said totalizer wheels, thereby locking said totalizer wheels against any additive or subtractive movement, means to rotate said control member when the totalizer is being moved into engagement with its actuating means so as to bring said slot adjacent the locking means to free all of the locking means from locking engagement with the totalizer wheels.
